Expression of miR-145 in urothelial carcinoma tissues. a Urothelial carcinoma of the bladder tissues. Urothelial carcinomas were histologically classified in to low grade and high grade (sq. diff.: squamous differentiation, gl. diff. :glandular differentiation, N.E. diff.: neuroendocrine differentiation) (Hematoxylin-eosin staining). b qRT-PCR analysis of the urothelial carcinoma tissues showed that miR-145 highly expressed in low grade than high grade carcinomas. (*p < 0.05, low grade v.s. high grade)
